Abstract

The present invention aims to provide an electromagnetic clutch capable of decreasing the impact noise generated when the armature plate and the driving rotor are coupled. The present invention further aims to provide a compressor equipped with this electromagnetic clutch.
An electromagnetic clutch in the present invention comprises a driving rotor including a coil, and an armature having an armature plate that is disposed facing this driving rotor and having the same axis of rotational thereas, and when a voltage is applied to excite coil, the end face of driving rotor and the armature plate are attached together by coil's magnetic force, thereby coupling driving rotor and armature. Armature plate comprises a plurality of metal thin plates (plate members) laminated together, and at least a part of the plate members being connected each other.
